Feature:1. [Innovative Design] The centering dial indicator is a new measuring tool that utilizes lever to transmit the relative position of workpiece center to the dial indicator, converting it into pointer angular displacement, precise, simple, and visible.2. [Measurement Range] This centering dial indicator features 0 to 0.15 inch measurement range and 0.0005 inch resolution, allows for quick and accurate centering in boring and milling setups on horizontal or vertical machines.3. [Easy to Use] Simply replace the feeler to operate at an angle from horizontal to vertical and from inner diameter to outer diameter without any changes.4. [Stable Indicator Position] The surface of the indicator remains stationary at any desired position while the machine spindle rotates, allowing the operator to position the worktable accurately.5. [Versatile Usage] This indicator can quickly place the workpiece or fixture at the center of the milling machine, widely used in various types of machining for center positioning measurement.Specification:Item Type: Centering Dial IndicatorMaterial: Aluminum AlloyStorage Box Material: WoodMeasurement Range: 0-0.15 InchScale: 0.0005 Inch.Package List:1 x Centering Dial Indicator1 x Center Point Feeler3 x Straight Feeler (2in, 4in, 6in)3 x Curved Feeler (2in, 4in, 6in)1 x Restraint Rod2 x Wrench1 x Instruction Manual1 x Storage Box
